* Add procmon plugin with live process panel New Noctalia plugin: bar widget shows CPU/RAM usage and process count; floating panel has a sortable, searchable process table with per-process kill. Background service samples ps and /proc stats and publishes via plugin state. * Throttle data-driven panel renders Rebuild table at most every 500ms to stay within the panel update CPU budget. User interactions still render immediately; only state watches and the tick go through maybeRender(). * Update procmon deps and fix timestamp precision Document head, grep, and cat as required commands. Correct refresh interval default to 1000 ms. Sample refreshedAtMs in milliseconds. * Add keyboard navigation and reduce CPU sampling - Panel: arrow keys move cursor, Ctrl+D kills selected, Ctrl+F focuses filter - Service: sample /proc stats every 1s, ps every 2s; 2s render floor - Widget: handle vertical bars, truncate text, use valid theme color - Bump version to 0.4.0, plugin_api 13
